# Delta14C in soil CO2 efflux from Harvard Forest

### Description

Measurements of Delta14C in soil CO2 efflux conducted at Harvard Forest, USA, between 1996 and 2010.

### Usage

1 |

### Format

A data frame with the following 3 variables.

`Year`

A numeric vector with the date of measurement in years

`D14C`

A numeric vector with the value of the Delta 14C value measured in CO2 efflux in per mil

`Site`

A factor indicating the site where measurements were made. NWN: Northwest Near, Drydown: Rainfall exclusion experiment.

### Details

Samples for isotopic measurements of soil CO2 efflux were collected from chambers that enclosed an air headspace in contact with the soil surface in the absence of vegetation using a closed dynamic chamber system to collect accumulated CO2 in stainless steel traps with a molecular sieve inside. See Sierra et al. (2012) for additional details.
